Abstract In order to protect residents in the Laugneri residential area from block slips and landslides, the municipality of Weggis has implemented a novel protective structure on steep terrain as part of its natural hazards master plan. Potential dynamic impacts are absorbed by the reinforced earth protective dam and transferred to the stable rock substrate […]
1. Summary The following article describes the redesign of an existing harbour promenade in the Lower Elbe area in order to increase the attractiveness of the harbour area, open up the former exclusively commercial harbour area and integrate the harbour into city life. This requires raising the ground level. Due to the low-bearing soil layers
Abstract Due to rapid advances in computing technology, it is now possible to process extremely large amounts of data in a short period of time. Accordingly, it is now feasible to use photogrammetric methods, with the aid of drones, to solve geotechnical engineering problems and open up new fields of application for practical use, or

Introduction Geotextiles used as filters must be dimensioned in such a way that the soil to be filtered is protected from erosion, the load-bearing grain structure is kept stable, the passage of fine grains is only permitted to a non-critical extent so that clogging – the accumulation of fine material on the filter – is

Two practical examples are used to explain waterproofing with plastic sealing membranes and the use of geosynthetics. The new section of the A 72 motorway south of Leipzig runs over challenging subsoil with problematic geology. The area is a landscape left behind by lignite mining in the 20th century – surrounded by partially filled former
Abstract In surface-parallel layered systems, such as surface sealing of landfills, geogrids are used to make these systems steeper. The geogrids absorb high tensile forces, which are anchored at the crest of the embankment in so-called anchor trenches. The previous design approach of EBGEO (2010) contains a number of assumptions that must be considered overly

Dr.-Ing. S. Schwerdt, Magdeburg-Stendal University of Applied Sciences Summary When designing geosynthetic reinforcements to bridge earth failures, the required anchoring and overlap lengths must be determined in addition to the tensile force. When designing reinforcements using biaxially anisotropic reinforcements, the question arises as to how the load is transferred at the edges of the reinforcement.
Current developments 1. Introduction The DIN EN 13249 ff (12/2016) series of standards regulates the functions, function-related essential characteristics and applicable test methods for geosynthetics. The functions and applications are defined in DIN EN ISO 10318-1 (10/2018 edition) and the associated pictograms are standardised in DIN EN ISO 10318-2 (10/2018 edition). Fig. 1a: Functions according

Introduction In addition to the recommendations for the design and calculation of earth structures reinforced with geosynthetics – EBGEO of the German Society for Geotechnical Engineering (DGGT) (DGGT), the information sheet on the use of geosynthetics in earthworks for road construction (M Geok E), which has been developed since 1995 under the leadership of the
